On a trip to NY my sister made reservations for 2 rooms for us as a convenience to me as my time was limited. When we arrived at the Hilton Newark Airport hotel, I asked to have the reservation changed to my own name as I was paying for the stay for both rooms, and that as my Hilton Honors number had expired, I wanted to obtain a new HH number, and have the stay credited to the new number. The agent took down all of my information, said she would be happy to take care of it, that it was not a problem. I received the new HH number which was delivered to my door a few minutes later. When we returned from our vacation, I checked my HH account, and found that the stay had not been credited to my HH account. I contacted Customer Care, and they opened a "case" with all of the details to get the matter cleared up, and the agent assured me that it would be corrected and that an e-mail with the resolution would be sent to me w/in 5-10 days. 3 weeks later I had not received the e-mail and called Customer Care. It took about 30 min to be transferred to a supervisor, who said they could not make the change in the reservation due to the terms and conditions. I re-explained the agreement by the agent at the hotel to update the reservation and the other details. The supervisor advised they could not make the change. She did credit my account with some "good will" points for my trouble, however they did not equal the amount of points I would have earned had the matter been corrected. Word of warning - stand at the desk and insist that all corrections be made immediately while you wait to prevent this kind of problem. I am very disappointed that after multiple phone calls and time spent to resolve this on my end, the HH program did not to the right thing. I paid for the room, my company discount was used, and my HH plan was in place. This was a waste of my time, a failure on the part of the hotel, and a failure of HH program not to resolve it satisfactorily.
